Recommended separation distance between portable and mobile RF communications
equipment and the Invia Motion pump
The Invia Motion pump is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the Invia Motion pump can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Invia Motion pump as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommened separation dis-
tance (d) in meters (m) can be estimated using the equation applicable to the frequency of the transmitter,
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
